To whom t may cof/warm l Be it `hown that I, JOHN F. OCoNNoR,

Chicago, in the county ot @ook and State of illinois, have invented a certain new and useful Improvement in Drafteltiggingtof which the following is a full, clear, conc1se, and exact description, reference being1 had to the accompanying drawings, forming a part of this specication.

' This invention relates to improvements in draft riggings.

` @ne object of the invention is to provide a draft ri ging wherein are employed movable castings or plates having stop shoulders thereon.

in the novel combinations of the parts and devices herein shown, described and claimed. lin the drawingI forming a` part of this specication, Figure 1 is a vertical, longitudinal section oi a portion of a car showing my'. improvements in connection therewith. Fig. 2 is ahorizontal, lon 'tudinal Section of the structure illustrate taken on the line 2-2 thereof. And Figs..

A3` and. t are vertical, transverse sectional views taken on the lines 3'3 and l-ehre spectively, if-Fig. 1.

`Referrinp; to said drawing, -10 denote charninilcenter;y sills of a car,tl1e same being slotted 'as indicated at v11,'to accommodate the bach and forth movements of a cou ler Y key 12. Upper andA lower platesv 13 an 14 are secured to the topsandbottoms of said sills, asindicated inA Figs. 1, 2 and 4L, said plates preferably forming a part ot the bol in Fig. 1 and ster of the car.. Secured tosaid plates 13 and U Y la are forwardly extendedl upper and lower a citizen of the Unlted States, residing atri.-

castings 15 and 16, the latter at their torward ends being rigidly secured to the centers of upper and lower cross plates l?" and 18 secured to the top and bottom Hanges, respectlvely ot the sills. The castin s or bars 15 and 16 are provided with vertically ahned, substantially rectangular openings 19 and 20, the pertorations 19 being adapted receive a square bar 21 and the per orations 26, a similar bar 22, said bars 21 and 22 being supported by any suitable means such as the cotters 23 that ass through bosses or enlargements 724i on t e lower castl ing 16. 'llhe bars 21 and 22 have mountedv thereon, between the castings 15 and 16, blocks 25 and 26, the block 25 being prei:- erably rounded, as indicated at' 2T, onits front and rear faces'A and against which bear the intermediate followers 28 and `294 of a tandem spring gear, 'The front main lol@ lower'30 ot the tandem gear bears against the rear or inner face ot vthe block 26. Ylhe rear main follower 3l of the tandem gear normally bears against the front edges ci vertically extending webs 32-f32 that preterably are termed inte al with the bars 15 and 16 (See` lF-ig'04 t Suitable springs 33-33 are interposed between the sets et followers and 28and 29 and 31.

Connected to the draw bar3l by means of the coupler he. 12, are' castings or plates 35-35. Each ot the castings or plates, 35 is in the torni ofthe usual ri 'dtandem stop castings, 'that is to say, it 1s provided withmain iront and rear stops 36 and '37' intermediate main stops 38 and 39; and

limiting stops l0, 41, 4t2 and topposite the main stops 36, 38, 39 and 37, respectively. As apparent from an'inspection ot liig. 2, the followers 30, 28', 29 and 31 normally engage the main stops 36, 38, 39 and 37, Ifespectively. The castings 35-35 engagegthe inner faces of the sills 10 and slide with respect thereto. The forward ends of said castings are supported by the, coupler key lll 12- and-the rear ends of said lcastings are supported by the cross plateale,

In operation, upon forward or draft movement of the draw bar, it is apparent that the followers 30 and 29 will be held stationary by the iixed blocks 26 and 25. The remaining followers 28a11d 31 will be pulled forwardly through the instrumentality of the castings and such forward movement will continue until the limiting-stops and 42 engage the followers 30 and 29, respectively. In other words,the draft movement is limited by the castings which move in unison with the draw bar. Upon inward or buifing movement of the draw' bar, 1t 1s ap parent that the followers 28 and 31 will remain stationary since they are held by, the block 25 andwebs 32', respectively. The remaining followers 30 and 29 will be forced inwardly by means of the castin s 35 and such inward movement will continue until the rear face 45 of the draw bar butt engages thefront face 46 of the block 26 and the limiting stops 41 and 43 engage the followers 28V and 31, respectively. From the foregoing, it will be seen that the castings 25 also limit the inward movement of the draw bar and the compression of the springs.

The parts are shown assembled in the drawing. Io remove the same, it is apparent that the keys 12, 21 and 22 are first taken out whereupon the castings 35, springs and followers and the blocks 25 and 26 can be removed forwardly as a unit. The parts are assembled in the reverse manner as will be obvious. lIt is apparent that -the followers and springs are supported and guided by the lower har or casting 16.

Although I have herein shown and described what I now consider the preferred embodiment of the invention, the same is merely illustrative and I contemplate all l changes and modifications that come, within the scope of the claims appended hereto.

I claim:

1. In a draft -rigging, the combination with a draw bar, and cushioning mechanism including followers, ofmeans connected with the draw bar for actuating said followers, said means having a series of shoulders thereon and limiting stops.

2.- In a draft rigging, the combination with a draw bar, and a series of centrally located fixed abutments, of cushioning means including followers, interposed between and normally engaging said fixed abutments, and

'castings coperating with said followers at their ends, the castings having a plurality of stop shoulders and being slidably mountd and adapted to be actuated by the draw 3. In a draft rigging, the combination with a draw bar, fixed abutments and followers engaging said abutments, of movable plates for actuating the followers, said plates asomo? having main and limiting stop shoulders for cooperation with said followers.

4. In a draft rigging, the combination with a draw bar, three centrally located fixed abutments providing a pair of pockets therebetween, tandem arranged springs and followers within said pockets, of slidably mounted side members coperating with said followers, said side members being movable in unison with the draw bar and having means thereon for limiting the compression of the springs.

5. In a railway draft rigging, the combination with spaced parallel draft sills, of a plurality of longitudinally spaced, fixed abutments disposed between said .sills and spaced therefrom, of cushioning means including followers interposed between and normally engaging said fixed abutments, and a pair of castings mounted betweenthe sills, each of said castings being adapted to slide on the inner face of a sill and interposed between the latter and adjacent ends of the followers, each of said castings having vertically extending shoulders engaging' the followers for actuating the same, a draw bar, and means for operatively connecting said-draw bar and castings.

6. In a draft rigging, the combination with tandem arranged springs'and followers, and xed abutments cooperating with said followers, of castings having tandem arranged stop shoulders thereon coperable with said followers, said castings being longitudinally slidable, said stop castings being provided with limiting stops to thereby limit the compression of the springs. i
